[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] like Figure 1-4 As shown, a mixing device for water-soluble fertilizer raw materials includes a hopper 1 and a rotating structure. The hopper 1 is cylindrical, and a top cover 2 is provided at the upper end of the hopper 1. A plurality of feed pipes 4 are provided on the side of the hopper 1. Various raw materials enter the hopper 1 from the feed pipes 4. A discharge pipe 5 is provided at the bottom of the hopper 1. The discharge pipe 5 can directly lead to a dissolution tank or a stirring tank. A bracket 11 is provided in the middle of the hopper 1. The rotating structure is rotatably connected to the bracket 11. A spiral plate 14 is provided on the side of the rotating structure. Various raw materials roll down along the curved surface of the spiral plate 14 and are scattered to the bottom of the hopper 1. The impact of the raw materials and their own weight will drive the rotating structure where the spiral plate 14 is located to rotate, so that the various raw materials are evenly scattered following the rotation of the rotating structure, thereby ensuring that the various raw materials are evenly mixed.

[0027] In the above embodiment, a shaft sleeve 13 is provided in the middle of the rotating structure, and the spiral plates 14 are arranged in a circular array on the side of the shaft sleeve 13. A rotating shaft 12 is provided at the upper end of the bracket 11, and the shaft sleeve 13 is rotatably connected to the rotating shaft 12, so that the spiral plates 14 can rotate around the rotating shaft 12 to evenly scatter the raw materials; the adjacent spiral plates 14 intersect in the vertical direction to prevent the raw materials from directly passing through the spiral plates 14 when falling, thereby improving the uniformity of raw material scattering; the inner wall of the feed pipe 4 is tangent to the inner wall of the hopper 1, and the raw materials have a certain speed when entering from the feed pipe 4. The raw materials will move forward for a distance along the inner wall of the hopper 1, and then approach the middle of the hopper 1 under the mutual squeezing of multiple raw materials, and finally fall onto the spiral plate 14, so that the multiple raw materials have been preliminarily mixed above the rotating structure, further improving the uniformity of the final mixture. Uniformity; an annular baffle 15 is provided on the inner wall of the hopper 1, and the annular baffle 15 is located between the feed pipe 4 and the rotating structure, which can not only provide a preliminary mixing platform for the raw materials entering the hopper 1, but also concentrate the raw materials to the middle of the hopper 1 to prevent the raw materials from falling directly from between the rotating structure and the inner wall of the hopper 1, thereby affecting the mixing effect; the annular baffle 15 is inclined downward from the outside to the inside to prevent the raw materials from piling up and make the raw materials naturally gather in the middle of the hopper 1; the inner diameter of the annular baffle 15 is smaller than the outer diameter of the rotating structure to ensure that when the raw materials fall from the annular baffle 15, they will not vertically pass between the annular baffle 15 and the rotating structure; the feeding direction of the feed pipe 4 is consistent with the rotation direction of the rotating structure to avoid the raw materials from directly passing obliquely between the spiral plates 14 after entering the hopper 1, thereby affecting the mixing effect.

[0028] In the above embodiment, a dryer 3 is provided on the top cover 2, and the dryer 3 is connected to the inside of the hopper 1, which can not only provide drying for the raw materials in the hopper 1, but also generate airflow to drive the spiral plate 14 to rotate, thereby improving the uniformity of the mixing; a discharge pipe 6 is provided on the side of the discharge pipe 5, and the mixed raw materials can be put into a bag and sealed for convenient use next time; a first pull-out plate 9 is provided between the discharge pipe 5 and the discharge pipe 6, and the first pull-out plate 9 can open and close the discharge pipe 6; a second pull-out plate 10 is provided on the discharge pipe 5, and the second pull-out plate 10 can open and close the discharge pipe 5, and can be controlled to switch to unloading or discharging at any time; a vibrator 7 is provided on the side of the discharge pipe 5 to prevent some damp raw materials from blocking the discharge pipe 5; a button 8 is provided on the vibrator 7, and the vibrator 7 can be manually started when the material is blocked.

[0029] Description of the working method of this utility model:

[0030] Urea, potassium dihydrogen phosphate and potassium nitrate and other water-soluble fertilizer raw materials are connected to different feed pipes 4 for pumping. The different feed pipes 4 used are distributed as evenly as possible to provide buffer space for the raw materials after entering the hopper 1, so as to avoid a large amount of raw materials from piling up together when being pumped into the hopper 1 at the same time, thereby affecting the mixing effect. After entering the hopper 1 in a counterclockwise direction, the various raw materials continue to move forward along the inner wall of the hopper 1 for a distance, and then fall onto the annular baffle 15, and gather toward the middle of the hopper 1 under the action of the inclined surface of the annular baffle 15; after the raw materials fall from the annular baffle 15, they are received by the spiral plate 14, and the raw materials themselves have a certain speed, which impacts the spiral plate 14, which will drive the spiral plate 14 to rotate counterclockwise, and the raw materials themselves also have a certain weight, which will help the rotation of the spiral plate 14; under the rotation and scattering of the spiral plate 14, the various raw materials go down in the spiral direction and are spirally scattered to the bottom of the hopper 1, ensuring that the various raw materials are mixed evenly, and finally gather at the discharge pipe 5 for unloading or discharging. The device can be directly mounted on the dissolution tank to dissolve and pump the raw materials according to the needs of agricultural spraying. If the mixed raw materials exceed the needs of agricultural spraying, they can be packed into bags through the discharge pipe 6 and sealed to avoid moisture for subsequent use.

[0031] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
